power electronics and drives

a) A 60 kW, 240 V, 1800 rpm separately excited de motor is controlled by a converter, as shown in Figure 3. The field current is maintained constant at I,=1.5 A and the machine back emf constant is K, =0.81 V/A rad/s. The armature resistance is R =0.2 Q and the viscous friction constant is B = 0.3 Nm.rad/s. The amplification of the speed sensor is K, = 93 mV/rad/s and the gain of the power controller is K2 = 110. i. Determine the rated torque of the motor, T¿(s). ii. Determine the reference voltage, V,(s) to drive the motor at the rated speed. TL(S) V,(8) K,I, 1 1 K2 w(s) R„(87g + 1) B(s7m + 1) K,I K1 Figure 3
